A Guide to Holter Monitoring

The Nasiff CardioCard Holter Recorder

Why Holter Monitoring?

If you have signs or symptoms of a heart problem, such as an irregular heartbeat (arrhythmia), your doctor may order a test called an electrocardiogram. The electrocardiogram is a brief, non-invasive test using an ECG Machine in which electrodes taped to your body check your heart’s rhythm.

Sometimes an electrocardiogram fails to detect any irregularities in your heart rhythm during the brief examination. If your symptoms suggest an occasionally irregular heart rhythm is causing your medical condition, your doctor may recommend wearing a Holter monitor for one to three days. While the ECG Machine only analyzes heart rhythm for a few minutes, the Holter monitor constantly monitors heart rhythm throughout the day. The Holter monitor will  record abnormal heart rhythms regardless of the time of day it occurs.

Using the Holter Monitor

A Holter monitor is a small, wearable device that records your heart rhythm over one to three days. During that time, the device records all heartbeats. The Holter monitor consists of electrodes that are attached to your chest with adhesive and then connected to a small recording device you wear at all times. The process is similar to receive a test with an ECG machine; however, you keep the electrodes attached to your body at all times.

Your doctor uses information captured on the Holter monitor’s recording device to determine if you have a heart rhythm problem. Although wearing a Holter monitor might seem inconvenient, this important test may help diagnose your condition.

Why EKG?

Why Does the Doctor Give Patient’s an EKG?

An electrocardiogram – abbreviated as either EKG or ECG – is a test that records the heart’s electrical activity and turns it into a graph that can be read and analyzed. The electrical impulse that travels through the heart is what causes the heart muscle to contract and pump blood. An EKG is one of the many important vital signs tests in medicine because it provides clues to your heart health. It is used to determine if the electrical activity is normal. These recordings tell you about current health problems, such as heart rhythm problems, that might require a pacemaker or drug therapy. Or identify problems that occurred in the past, such as an old, and sometimes silent (unnoticed) heart attach, a heart enlargement that can lead to heart failure, and many other important conditions. It also can tell if a heart attack is in progress, so that drugs can be given to reduce heart damage and improve survival.

The EKG is an important part of a complete medical checkup.  The test cannot predict your heart’s future, but along with a  family and personal history, it can help in decision-making to keep you in the best possible cardiopulmonary health.

When should you have an EKG?

If you are experiencing any chest pains, fainting, dizziness, or shortness of breath, you should consult your doctor right away. He or she may send you directly to an emergency room, where an EKG is one way to determine if you are having a heart attack.

If you are symptom-free, how often you get an EKG will depend on your doctor, who will take into account your history, age, and other heart disease risk factors such as family history, diabetes, and smoking.

The electrocardiogram is a simple, painless, and very safe test done while you are lying face up on an examining table. A machine with numerous long cables (which look similar to electrical wires) nearby. They allow the signals of your beating heart to be read by the electrocardiograph machine.

To pick up the signals, small plastic tabs (with conductors that contract your skin) are stuck on your skin in at least 10 different spots – one on each of your limbs and on six locations around your chest. These patches – usually electrodes that detect electrical current, attach to the cables that lead to the machine. The machine turns the signals into wavy lines that form a graph, a representation of your heart’s electrical activity.

The total examination time, from entering the room until the test is completed, is usually 15-20 minutes. EKG machines often have computerized equipment that analyze the scan automatically, but doctors always like to check the results themselves. In emergencies, you can receive immediate results.

An EKG can provide valuable information that can help your doctor keep you well, and possibly save your life.
